Matching the bottom and top from two different brittle ice runs from last year.

This picture shows how we match the bottom and top from two different brittle ice runs from last year. The index mark is visible on the shallower piece to the left. Despite the brittle ice and the netting, we were able to keep track of the absolute depth from the top by using index marks before we cut the cores to 1 m length.
